Jacksonville placed Manhertz on the reserve/COVID-19 list Monday after he tested positive for the virus, Tom Pelissero of NFL Network reports.
Manhertz wasn't targeted on 27 offensive snaps during Sunday's loss to the Jets, and he's now looks to be at risk of missing the Jaguars' Week 17 game against the Patriots. Luke Farrell (illness) also landed on the COVID-19 list, leaving James O'Shaughnessy and Jacob Hollister as the only available tight ends on the roster.
